PROBLEM TO BE SOLVED: To prevent tone quality deterioration due to occurrence of unnecessary vibration in a frame etc. and temperature rising in a magnetic circuit. SOLUTION: A speaker device comprises: a first frame 53 for supporting a vibration system component such as a vibration cone 43; and a second frame 59 for supporting a magnetic circuit 57 for driving the vibration system component, in separate bodies. The second frame 59 is coupled to the first frame 53 through a packing 75, and forms a sealing space covering the back of the vibration cone 43. COPYRIGHT: (C)2007,JPO&INPIT
